There is also the possibility that thermal or > mechanical shock could demagnetize the magnet. If the coupling between the magnet and the surrounding coils is good, the magnet could be nearly stopped by the first coil, but pushed on by the gas. If the magnet approaches at high velocity, a high voltage is induced, and energy is absorbed, slowing the magnet -- but not stopping it because the induced voltage is reduced. finally the voltage will fall so low that the coupling circuits will not work. For maximum efficiency neodydmium iron magnets would be used which are very difficult to demagnetize. The device is suppoised ot use low temperature, waste heaqt gas. Mike Carrell > > > >
